Original GitHub issue: https://github.com/netbootxyz/netboot.xyz/issues/1105

Describe the bug
After netbooting into flatcar, an IP address is no longer assigned.No IP address means no network/internet connection. Which causes any attempt to use flatcar-install or coreos-installer script(s) to install the OS to disk to fail, because they are unable to download the required images.

To Reproduce

setup pfsense as a netboot server https://figura.im/posts/2020/01/pfsense-as-a-netboot.xyz-server/
from netboot main menu select live network install
select container linux by flatcar stable
after flatcar boots & at command prompt type flatcar-install -d /dev/sda

Expected behavior

expect required images to download, and be installed on selected disk. Instead script fails because image is unable to be downloaded.

Screenshots

Additional context
When I boot Fedora CoreOS (or Ubuntu) from an ISO, an IP address is assigned and I'm able to connect to the internet or my internal network to download the required images.

I was able to get networking using Proxmox... are you using DHCP and any info about the network/hardware you are using? It sounds like networking may not be getting detected, but it should normally work.

@antonym I am using DHCP, the same config described here: https://figura.im/posts/2020/01/pfsense-as-a-netboot.xyz-server/
I should have mentioned that I am doing a bare metal install on a HP ProDesk 405 G6 Desktop Mini PC
The network adapter is a Realtek RTL8111 (when i boot it up with ubuntu)

I think it may be a driver issue?
